1.9.1 Configuring an Oracle Linux 5 System to Use yum with ULN

If your Oracle Linux 5 system is registered with ULN, you can use yum instead of up2date to download and install packages. If you have installed a full update since Oracle Linux 5.6 was released on January 20, 2010, your system should already be able to use yum with ULN.

To enable yum support, install yum-rhn-plugin.

# up2date --install yum-rhn-plugin 

With the plugin installed, you can immediately start to use yum instead of up2date.
